Correct Answer: 1, 3, 2, 4

Solution : Given:
1. Forbes  2. Forest  3. Forensic  4. Formation

Step 1: Compare the first letter of each word. Since all the words start with the same letter F , we move on to the next letter.
Step 2: Let's move to the second letter of each word. Since all the words have the same second and third letters o and r , we move on to the next letter.
Step 3: The fourth letter of each word is: b, e, e, m . Based on the alphabetical order of these letters, we can arrange them: For b es, For e st, For e nsic, For m ation.
Step 4: Compare the fifth letter of (Fore s t, Fore n sic). Fore n sic will come before Fore s t in the sequence as n comes before s in the alphabetical system.

So, the sequence is Forbes, Forensic, Forest, Formation, or 1, 3, 2, 4. Hence, the fourth option is correct.
